Geology Walk at Saligo

18 brave souls turned out on a dreich afternoon to learn more about the wide range of geological features exposed at the bay. However, the rain wasn't as heavy as we had first feared and the dunes gave us some shelter from the strengthening SE wind.

There's so much to see in a small area - from Silurian-age (440 million year old) igneous rocks (a biotite-diorite stock) intruded into 700 million-year old turbiditic metasandstones and metamudstones themselves folded 470 million years ago in the Caledonian mountain building (orogenic) event. And for good measure, a 60 million-year old 10m thick gabbroic dyke with chilled and baked margins evidencing the initiation of the opening of the North Atlantic ocean.

Hunting for flint glacial erratices was very sucesful now that all that horrible sandy stuff has been washed away exposing all the wonderful rocks! The highlight for some folk was the audience-participation bit where Dave had 'volunteers' strung out across the beach in a time-line from the big bang to the stone age.

News Flash - The lobster has grown!

Old skin - can you believe it pulls itself out of this
 all squishy and soft before hardening its new skin
I came into the centre this morning, went round all the tanks to check all the creatures were happy.  Saw tentacles poking out of the lobsters tube - all fine. Then I noticed a half buried lobster body in the sand, a moment of confusion before the realisation that our fella must have shed its coat and grown.

I haven't seen its full new size yet, the claws look big but it still fits in the tube, so that's good, but will feed it this afternoon and see how big it is.  The creatures are all doing very nicely this year, so well worth a trip to the centre to have a look at all the little creatures that happily live off Islay's shores.

Dune Delights at Sanaigmore

Last Sundays rAmble at Sanaigmore 12th June 2016

Germander Speedwell
A dune walk, always a chance for a delight of colour.  Buttercup and Birds-foot Trefoil with the wonderful bright blue of Germander Speedwell puncturing through the yellow.  A number of mermaids purses empty, dried and light as a feather scattered on the grass where they had been blown from the shore.  Thrift in flower and Lady's Bedstraw and Thyme just bursting forth with blooms that will be busy for the next couple of months.  Around the rocky outcrops and on the inland side Heather, wind pruned to a tight cropped carpet was interspersed with Lousewort and the first spikes of Heath Spotted Orchid, the dry weather of late had not suited the tiny Stonecrop with one flower clinging to existence in a tiny pocket of soil in a rock crevice.

Marsh Orchid?
Marsh Cinquefoil
The once wetter areas had Marsh Pennywort, Ragged Robin, Marsh Marigold and Forget-me-not.  The wind was a bit brisk for butterflies but a nice Green-veined White obliged for a photograph. 
Green-veined White
A large hawker dragonfly zoomed past but wasn't for identifying and one of our party saw a Painted Lady.  Painted Lady's are migratory pushing up from the continent, I hear the weather in the south is wet so they have bypassed the soggy places for sunny dry Islay.

The small Common Gull colony had 5-6 chicks perched a top the pebbles, with peeping Oystercatchers.  Good views of Ringed Plovers, Wheatear, we watched the Skylarks sing on the way up and the meadow Pipits sing as they parachuted down.

A first and a highlight of the afternoon was a shrew, bold as you like scurrying across the heather and into the longer grass.

Flowers: Birds-foot Trefoil; Thyme; Lady's bedstraw; Thrift; Tormentil; Germander Speedwell; Marsh Cinquefoil; Ragged Robin; Forget-me-not spp; Marsh Pennywort;
English Stonecrop; Heath Spotted Orchid; other hybrid spotted orchid; Lousewort.

Sunday ramble - Solam 'plague' village 5th June 2106

A report on our walk to Solam our first Sunday ramble of the season, better late than never!

A very sunny, warm day for our first walk of the season up to the old village of Solum.  Our small band of ramblers travelled our way through farmland, woodland, still vibrant with the colours of spring flowers, bluebells and pignut, the leaves bursting forth on the branches.  Hazel, Birch, some Oak, Alder and Sycamore the main tree contingent.  The grasslands were attracting Small Heath butterfly, Green-veined White and a fast flying russety orange type which didn't sit still to see, but a Fritillary I assumed perhaps Marsh Frit.  The heat of the day gave all the butterflies a speed I could not match with my small net!  We saw two Clouded Buff (day flying moth) a nice addition to the list.  Above the woodland, patches of wet heath with a bountiful flourish of cotton grass over slightly de-hydrated sphagnum mosses with butterwort and sundews vying for nutrient full midges to entrap.

Round leaved Sundew with entrapped midges
We sort out the rock carvings, perhaps created by the shepherd who once inhabited the old steading, supposedly, 'Rabbie Burns' and the profile of the lady.  We discussed the legend of the plague village, where lies the truth and the fiction of a good tale. 
The lady in the rock

Carpets of Bog Cotton (Cotton grass)

The old walls and rocks of the older village dwellings emerge from the grassland blanket that hugs and wraps around the rocks with nature finding niches in all the nooks and crannies, lichens and mosses and tree saplings finding a roothold in the mosses and rock crevices.

English Stonecrop

Foxglove and Tormentil

Rowan sapling

Lichen and moss hugging the rocks
2 Golden Eagle were seen soaring on the hot thermals of the day in the distance, circling high, and a lovely yellowhammer sat perched singing on top of the old shepherds house.

A great first foray into Islay's wondrous nature of 2016, hopefully the first of may a pleasant, sociable walk with local Islay folk and visitors and showing them the beautiful, interesting and unexpected delights that Islay's natural history can provide.

Birds: 2 Golden Eagle; Yellow Hammer; White throat; Buzzard; Willow warbler.  Butterflies: Small Heath; ?Marsh Fritillary; Painted Lady; Peacock; Green-veined White; Clouded Buff (moth).

Flowers: Birds-foot Trefoil; Pignut; Bluebell; Tormentil; Butterwort; Round leaved Sundew; Heath Speedwell; Germander Speedwell; Lousewort; Heath Bedstraw; Cotton grass; Hazel; Downy Birch; Alder; Oak; Sycamore; Willow

Next Nature Walk - Solam, Plague Village, Nr. Ardbeg

Sunday Nature rAmbles start again this Sunday at 2pm
We will walk through field, wood, wet heath to the old village of Solam taking in the very varied plant life and wild nature, with a bit of history and find the hidden faces in the rocks.  A walk a little longer than our usual but well worth the effort, there were many Marsh Fritillery caterpillars at Easter so hoping we might see some butterflies out now, the sun looks to be set to shine so join us for a nature fest.  Everyone is very welcome. Meet in Ardbeg distiller car park.
£4 per person, families £10; INHT members £2

In search of Spring Squill

In search of Spring Squill - Becky discovered this flower in 2010 on one of her Islay coastal walks.  I remember seeing in on Oronsay many years ago and being captivated by its small beautiful blue star shaped flower and squiggly curling leaves.  It has taken me 6 years to finally find time to go in search of the Islay Squill.  With only one recent record of it south west of Saligo it is a relative rarity for Islay despite a general wide distribution through the nearby Hebridies.  The weather of late has been one of a perfect typical Islay Spring, dry and sunny, not like the rubbish cold and wet springs of the last couple of years, so long walks are a joy and with an excuse to get out Mandy (our centre manager) and I went on a quest.  There is so much to see, soon we saw a Marsh Fritillary butterfly, these are just beginning to emerge so look out for them over the next few weeks.   I will be looking forward to our first summer Sunday Ramble this weekend to Solam, near Ardbeg as we may get to see Marsh Frit.s too as I saw many caterpillars there at Easter.  Many flowers are out to enjoy, here's just some of the wonderous colour of last Sunday afternoon.

Finally after much walking I stumbled upon the perfect little blue flower on close cropped coastal pasture, 7 small flowering spikes only 6-7cm tall, then another 8 spikes on a separate patch.
Finally excitement, the treasure in our quest amongst the Tormentil and sheep dung

Spring Squill (Scillia verna)

A grand afternoon enjoying Islay's wonderful wildlife and weather.
